[0001] The present invention relates to the technical field of 3D printing, and in particular to a 3D printer and a transportation and debugging method thereof. Background Art

[0002] 3D printing, also known as additive manufacturing, is a technology that uses digital model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is often used to make models in the fields of mold manufacturing, industrial design, etc., and later gradually used for the direct manufacturing of some products. There are already parts printed using this technology.

[0003] Existing 3D printers usually include a shell and a main structure located inside the shell. The main structure supports the shell, and the shell protects the main structure. The shell and the main structure are fixedly connected to facilitate the transportation of the device. However, when the 3D printer is in operation, when the shell is vibrated by external force, the main structure fixedly connected to it will vibrate, which seriously affects the printing effect.

[0022] As an optional solution, the connecting mechanism further includes a second connecting component, wherein the second connecting component connects the supporting platform and the shell component, and the second connecting component and the first connecting component are arranged at intervals in the vertical direction.

[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0056] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0058] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0059] This embodiment provides a 3D printer, such as Figure 1 and Figure 2 As shown, the 3D printer includes a main body mechanism 10 and a shell mechanism 20, wherein the main body mechanism 10 includes a support platform 11 for installing a printer body (not shown in the figure), and the shell mechanism 20 is covered on the outside of the main body mechanism 10, so as to protect the main body mechanism 10 and prevent the printer body from being damaged by direct external collisions.

[0060] like Figure 2 As shown, the 3D printer also includes a connecting mechanism, which enables the main mechanism 10 and the shell mechanism 20 to have a first state and a second state. In the first state, the shell mechanism 20 and the main mechanism 10 are fixedly connected by the connecting mechanism; in the second state, the connecting mechanism is disassembled, and the shell mechanism 20 and the main mechanism 10 are separated. Therefore, during the transportation of the 3D printer, the shell mechanism 20 and the main mechanism 10 can be fixedly connected as a whole, so as to facilitate transportation; when the main mechanism 10 needs to work, the connecting mechanism is disassembled to separate the main mechanism 10 from the shell mechanism 20, so as to avoid the vibration of the shell mechanism 20 caused by the influence of external force being transmitted to the main mechanism 10, thereby ensuring a better printing effect.

[0061] Optionally, during the transportation of the 3D printer, the main body 10 is supported on a support surface (such as a surface in a transport vehicle that carries the 3D printer), and the shell 20 can be supported on the support surface or in a suspended state. When the lower end of the shell 20 is in a suspended state, it can prevent the main body and the shell from being damaged by the interaction of the connecting mechanism due to asynchronous vibration when the road is bumpy.

[0062] like Figure 1 and Figure 2 As shown, the shell mechanism 20 includes a bottom plate assembly 21 and a shell assembly 22, wherein the bottom plate assembly 21 is constructed in an annular shape and is arranged around the outer periphery of the support platform 11, and the shell assembly 22 is connected to the bottom plate assembly 21 and is covered on the outer side of the main mechanism 10. In this embodiment, the bottom plate assembly 21 is constructed as a rectangular frame structure. The shell assembly 22 includes a front panel 221, a rear panel, two side panels 222 and a top panel 223, the front panel 221 and the rear panel are arranged oppositely and are respectively located on the front and rear sides of the main mechanism 10, and the lower end of the front panel 221 and the lower end of the rear panel are both connected to the bottom plate assembly 21. The two side panels 222 are arranged oppositely and are respectively located on the left and right sides of the main mechanism 10, the lower end of the side panel 222 is connected to the bottom plate assembly 21, and the front and rear ends are respectively connected to the front panel 221 and the rear panel. The top panel 223 is disposed on the top of the main body 10 and is respectively connected to the front panel 221, the rear panel and the two side panels 222, so as to achieve comprehensive cover protection for the main body 10. In this embodiment, the front side panels 3121 include a main body panel 2211 and a movable panel 2212. The main body panel 2211 is provided with a window, which is opposite to the printer body. The movable panel 2212 is movably connected to the main body panel 2211 so as to be able to open and close the window, thereby facilitating the operator to operate the printer body.

[0063] like Figure 2 and Figure 3 As shown, the shell mechanism 20 also includes a first roller assembly 24, and the first roller assembly 24 is connected to the base assembly 21. By setting the first roller assembly 24, not only can the movement of the shell mechanism 20 be facilitated, and the relative position of the entire shell mechanism 20 and the main body mechanism 10 can be adjusted, but also the assembly process of the shell mechanism 20 is more convenient. In this embodiment, the first roller assembly 24 is installed below the base assembly 21. Optionally, the first roller assembly 24 includes a universal wheel. In this embodiment, the first roller assembly 24 includes four universal wheels. In other embodiments, the first roller assembly 24 may include three, five or more, which are not specifically limited here.

[0064] like Figure 2 and Figure 3As shown, the main body mechanism 10 also includes a second roller assembly 13, and the second roller assembly 13 is connected to the support platform 11. By providing the second roller assembly 13, not only can the movement of the entire main body mechanism 10 be facilitated, and the relative position of the entire shell mechanism 20 and the main body mechanism 10 can be adjusted, but also the assembly process of the main body mechanism 10 itself can be more convenient. In this embodiment, the second roller assembly 13 is installed below the support platform 11. Optionally, the second roller assembly 13 includes a universal wheel. In this embodiment, the second roller assembly 13 includes four universal wheels. In other embodiments, the second roller assembly 13 may include three, five or more, which are not specifically limited here.

[0065] like Figure 2 and Figure 3 As shown, the bottom plate assembly 21 includes a first bottom plate 211 and a second bottom plate 212, a portion of the housing assembly 22 is connected to the first bottom plate 211, and a portion of the housing assembly 22 is connected to the second bottom plate 212. The first bottom plate 211 has a notch in the circumference, and the second bottom plate 212 is detachably connected to the first bottom plate 211, so that the notch can be opened or blocked. When the second bottom plate 212 is removed from the first bottom plate 211, the main body mechanism 10 can be inserted into the housing mechanism 20 from the notch, and when the second bottom plate 212 is connected to the first bottom plate 211, the first bottom plate 211 and the second bottom plate 212 form a closed ring.

[0066] When assembling a 3D printer, the assembly of the components of the main body 10, the assembly of the partial shell assembly 22 and the first base plate 211, and the assembly of the partial shell assembly 22 and the second base plate 212 can be carried out simultaneously. After the main body 10 is assembled, it is pushed into the first base plate 211 from the notch of the first base plate 211 as a whole, and finally the second base plate 212 is connected to the first base plate 211. Through the above arrangement, not only the assembly efficiency of the 3D printer can be improved, but also the process of placing the main body 10 into the shell mechanism 20 does not require hoisting and lifting, thereby improving the assembly convenience of the 3D printer. In this embodiment, the first base plate 211 is constructed in a U shape so that the main body 10 can be loaded from the notch of the first base plate 211. Optionally, the first base plate 211 can be integrally formed, or it can be assembled from multiple strips, which is not limited here. Optionally, among the front side plate 3121 , the rear side plate 3121 and the two side panels 222 , one is connected to the second bottom plate 212 , and the other three are connected to the first bottom plate 211 .

[0067] like Figure 4As shown, the support platform 11 includes a support frame 111 and a carrier 112. The carrier 112 is installed on the top of the support frame 111 and is used to install the printer body. The support frame 111 can support the carrier 112 and the printer body to a suitable height, and the overall weight is relatively light; the carrier 112 provides a flat support surface, thereby supporting the printer body more stably. In this embodiment, the second roller assembly 13 is installed below the support frame 111.

[0068] like Figure 2 and Figure 4 As shown, the connection mechanism includes a first connection component 30 and a second connection component 40, the first connection component 30 connects the lower end of the support platform 11 and the shell mechanism 20, the second connection component 40 connects the upper end of the support platform 11 and the shell mechanism 20, and the first connection component 30 and the second connection component 40 are arranged at intervals in the vertical direction. In this embodiment, by providing the first connection component 30 and the second connection component 40 arranged in the vertical direction, not only can the reliable connection between the shell mechanism 20 and the support platform 11 be ensured, but also the force applied to the shell mechanism 20 is made more uniform, so as to avoid the shell mechanism 20 from tilting and falling due to road bumps during transportation, thereby ensuring the safety of the 3D printer during transportation.

[0069] In this embodiment, the first connecting assembly 30 connects the lower end of the support frame 111 and the lower end of the shell mechanism 20, and the second connecting assembly 40 connects the carrier 112 and the middle part of the shell mechanism 20. Specifically, the lower end of the support frame 111 has a crossbeam 1111, and the first connecting assembly 30 is connected to the crossbeam 1111. Optionally, two first connecting assemblies 30 are provided, and they are symmetrically arranged, so as to improve the uniformity of the force between the base plate assembly 21 and the support platform 11. In other embodiments, the number of the first connecting assemblies 30 can be flexibly set. Optionally, four second connecting assemblies 40 are provided, and the four second connecting assemblies 40 are symmetrically distributed, so as to further improve the uniformity of the force between the shell assembly 22 and the support platform 11. In other embodiments, the number of the second connecting assemblies 40 can be flexibly set as needed. In addition, it should be noted that when installing or disassembling the first connecting assembly 30 and the second connecting assembly 40, part of the shell assembly 22 can be disassembled, so as to improve the convenience of operation.

[0070] like Figure 2 , Figure 5-Figure 7As shown, the first connecting component 30 includes a first connecting member 31, and the first connecting member 31 includes a bottom 311 and a first extension 312. The first extension 312 is formed by extending from one end of the bottom 311. The first extension 312 is overlapped on the support platform 11 and connected to the support platform 11. The bottom 311 supports the bottom plate assembly 21 and is connected to the bottom plate assembly 21. Since the main body 10 is heavy and the shell 20 is relatively light, the first extension 312 is overlapped on the support platform 11, and the bottom 311 is supported on the lower side of the bottom plate assembly 21, which can play a good supporting role for the shell 20 and ensure the reliability of the connection between the shell 20 and the main body 10. In this embodiment, the first extension 312 is overlapped on the crossbeam 1111 at the lower end of the support frame 111.

[0071] like Figure 6 As shown, the first extension portion 312 includes a side plate 3121 and a top plate 3122, and the side plate 3121 connects the bottom 311 and the top plate 3122. The top plate 3122 is provided with a first connection hole 31221 extending axially along the first direction, and the first fastener penetrates the first connection hole 31221 and connects the top plate 3122 and the support platform 11. Specifically, the support platform 11 (i.e., the upper surface of the crossbeam 1111) is provided with a first matching hole corresponding to the first connection hole 31221, and the first fastener penetrates the first connection hole 31221 and the first matching hole to connect the top plate 3122 and the support platform 11. The side plate 3121 is provided with a second connection hole 31211 extending axially along the second direction, and the second fastener penetrates the second connection hole 31211 and connects the side plate 3121 and the support platform 11. Specifically, a second matching hole corresponding to the second connection hole 31211 is provided on the support platform 11 (i.e., the side surface of the crossbeam 1111), the second direction is arranged at an angle to the first direction, and the second fastener penetrates the second connection hole 31211 and the second matching hole to connect the side plate 3121 and the support platform 11. In other words, the first extension portion 312 in this embodiment is connected to the support platform 11 through two sets of fasteners with different axial directions, thereby improving the stability and reliability of the connection between the first connection member 31 and the support platform 11.

[0072] In this embodiment, the first direction and the second direction are perpendicular to each other, and the first direction is a vertical direction, and the second direction is a horizontal direction. In other embodiments, the first direction and the second direction may also form an acute angle. Figure 5 As shown, the top plate 3122 is horizontally arranged and overlapped on the upper surface of the beam 1111, and the side plate 3121 is vertically arranged and attached to the side surface of the beam 1111. Optionally, the number of the first connection holes 31221 on the top plate 3122 can be one, two, three or more. The number of the second connection holes 31211 on the side plate 3121 can also be one, two, three or more.

[0073] like Figure 6 As shown, a third connection hole 3111 is provided on the bottom 311 of the first connection member 31, a third matching hole 2111 corresponding to the third connection hole 3111 is provided on the bottom plate assembly 21, and the fastener passes through the third connection hole 3111 and the third matching hole 2111 to connect the bottom 311 and the bottom plate assembly 21. Optionally, the number of the third connection holes 3111 can be one, two, three or more, which is not limited here.

[0074] like Figure 6 As shown, the first connecting hole 31221 is a long hole extending along the second direction, and the third connecting hole 3111 is also a long hole extending along the second direction. Therefore, when the relative positions of the main body mechanism 10 and the shell mechanism 20 in the second direction have some deviations, or the first matching hole and the second matching hole on the main body mechanism 10 have deviations in processing, or the third matching hole 2111 on the base plate assembly 21 has deviations in processing, the setting of the long hole can compensate for the above deviations, thereby ensuring that the first connecting member 31 smoothly connects the main body mechanism 10 and the shell mechanism 20.

[0075] like Figure 6 As shown, the second connecting hole 31211 is a long hole extending along the third direction, and the third direction is perpendicular to the first direction and the second direction, that is, the third direction is also a horizontal direction. When the processing position of the second matching hole has a certain deviation along the third direction, the first connecting member 31 can also be ensured to be installed smoothly.

[0076] like Figure 5 and Figure 6 As shown, the first connecting member 31 also includes a reinforcing portion 315, and the reinforcing portion 315 connects the bottom 311 and the side plate 3121. Since the side plate 3121 and the bottom 311 are subjected to greater forces, the structural strength of the entire first connecting member 31 can be ensured by arranging the reinforcing portion 315 at the intersection of the two, thereby improving the reliability of the connection between the main mechanism 10 and the shell mechanism 20. In this embodiment, the reinforcing portion 315 is constructed as a sheet material and is perpendicular to the side plate 3121 and the bottom 311. Optionally, the reinforcing portion 315 can be connected to the bottom 311 and the side plate 3121 by welding. The number of reinforcing portions 315 can be one, two, three or more.

[0077] Alternatively, if Figure 7As shown, the overlapping width of the top plate 3122 and the support platform 11 is greater than the gap width between the bottom plate assembly 21 and the reinforcing portion 315. With such a configuration, on the one hand, the distance between the bottom plate assembly 21 and the support platform 11 is closer, which is beneficial to improving the structural compactness of the entire 3D printer; on the other hand, after the first fastener connecting the top plate 3122 and the crossbeam 1111 and the fastener connecting the bottom 311 and the bottom plate assembly 21 are removed, based on the above width relationship, the first connecting member 31 will not fall to the bottom of the support platform 11 at will and be difficult to remove. The specific method of removing the first connecting member 31 can be referred to the debugging method of the 3D printer below.

[0078] like Figure 7 As shown, the reinforcement portion 315 is provided with an inclined edge 3151 on one side facing the bottom plate assembly 21, and the inclined edge 3151 is inclined toward the support platform 11 from bottom to top. This arrangement facilitates the entire first connecting member 31 to be placed between the bottom plate assembly 21 and the support platform 11.

[0079] In this embodiment, Figure 6 As shown, the number of the first connection holes 31221 and the third connection holes 3111 are both three, and the number of the second connection holes 31211 is two. The three first connection holes 31221, the three third connection holes 3111, and the two second connection holes 31211 are all evenly arranged along the third direction, and the second connection holes 31211 are spaced apart from the reinforcement portion 315.

[0080] like Figure 5 and Figure 6 As shown, the first connecting member 31 further includes a second extension portion 313, which is formed by extending upward from the other end of the bottom 311. The second extension portion 313 can strengthen the overall structure of the first connecting member 31. Optionally, the bottom 311, the first extension portion 312 and the second extension portion 313 can be integrally formed by bending sheet metal, and the integrally formed structure makes the first connecting member 31 have a higher structural strength, thereby preventing it from being damaged during transportation of the 3D printer.

[0081] like Figure 6 Combined with Figure 5As shown, the second extension portion 313 is provided with a first long hole 3131 extending in the horizontal direction, the bottom plate assembly 21 is provided with a positioning hole 2112 corresponding to the first long hole 3131, and the first connecting assembly 30 further includes a positioning member, which penetrates the first long hole 3131 and is inserted into the positioning hole 2112, so as to be connected with the bottom plate assembly 21. When installing the first connecting member 31, the first long hole 3131 and the positioning hole 2112 can be firstly penetrated by the positioning member to locate the installation position of the first connecting member 31, so as to improve the installation efficiency of the first connecting member 31. In this embodiment, the first long hole 3131 extends along the third direction, so when installing the positioning member, the position of the first connecting member 31 in the third direction can be fine-tuned, thereby ensuring that the first connecting hole 31221 corresponds to the first matching hole in the third direction, and the third connecting hole 3111 corresponds to the third matching hole 2111 in the third direction, thereby ensuring that the first connecting member 31 is installed smoothly.

[0082] like Figure 7 As shown, along the axial direction of the first long hole 3131 (i.e., along the second direction), there is a gap 314 between the second extension portion 313 and the housing mechanism 20. Such a configuration can ensure that the bottom plate assembly 21 can be smoothly placed on the bottom 311, avoid the interference between the bottom plate assembly 21 and the second extension portion 313 during the process of placing the bottom plate assembly 21 on the bottom 311, and improve the convenience of assembly.

[0083] like Figure 2 and Figure 8 As shown, the second connection assembly 40 includes a second connection member 41 and a third connection member 42, the second connection member 41 is connected to the shell mechanism 20, the third connection member 42 is connected to the support platform 11, the second connection member 41 and the third connection member 42 are connected by a third fastener, and the connection position of the second connection member 41 and the third connection member 42 is adjustable. The processing of the structure used to connect the second connection assembly 40 on the main body mechanism 10 and the shell mechanism 20 may have deviations. After the first connection member 31 is installed, the position between the main body mechanism 10 and the shell mechanism 20 may have a certain deviation. In this embodiment, by setting the second connection assembly 40 as two parts, the connection position between the two parts is adjustable, that is, the above error can be compensated by adjusting the connection position of the two parts, thereby ensuring the smooth installation of the entire second connection assembly 40.

[0084] In this embodiment, Figure 2 and Figure 8 As shown, the second connecting member 41 is constructed in an L shape, and the second connecting member 41 includes a first plate 411 and a second plate 412. The third connecting member 42 is also constructed in an L shape, and the third connecting member 42 includes a third plate 421 and a fourth plate 422, wherein the first plate 411 is connected to the outer shell assembly 22, the third plate 421 is connected to the support platform 112, and the second plate 412 and the fourth plate 422 are attached and connected.

[0085] like Figure 8 As shown, one of the second connecting member 41 and the third connecting member 42 is provided with a second long hole 4221 extending in the horizontal direction, and the other of the second connecting member 41 and the third connecting member 42 is provided with a through hole 4121, and the third fastener penetrates the second long hole 4221 and the through hole 4121 to connect the second connecting member 41 and the third connecting member 42. When the relative distance between the shell mechanism 20 and the main body mechanism 10 has a deviation, the provision of the second long hole 4221 can compensate for the deviation, ensuring that the second connecting assembly 40 can be connected between the shell mechanism 20 and the main body mechanism 10. In this embodiment, the second long hole 4221 is provided on the fourth plate 422 of the third connecting member 42 and extends in the second direction, and the through hole 4121 is provided on the second plate 412 of the second connecting member 41. Optionally, the number of the through holes 4121 can be one, two or more. In other embodiments, the second long hole 4221 may be provided on the second plate 412 of the second connecting member 41 , and the through hole 4121 may be provided on the fourth plate 422 of the third connecting member 42 .

[0086] The second connecting assembly 40 also includes a fourth fastener and a fifth fastener, such as Figure 8 As shown, the second connecting member 41 is provided with a first mounting hole 4111, the third connecting member 42 is provided with a second mounting hole 4211, the fourth fastener is provided through the first mounting hole 4111 and connected to the housing mechanism 20, the fifth fastener is provided through the second mounting hole 4211 and connected to the supporting platform 11, and at least one of the first mounting hole 4111 and the second mounting hole 4211 is a long hole extending in the vertical direction. When there is a deviation in the relative position between the bearing platform 112 and the housing component 22 in the vertical direction, or there is a deviation in the hole processing on the housing component 22 for matching with the first mounting hole 4111, or there is a deviation in the hole processing on the bearing platform 112 for matching with the second mounting hole 4211, one of the first mounting hole 4111 and the second mounting hole 4211 is set as a long hole extending in the vertical direction to compensate for the deviation, so as to ensure that the second connecting component 40 can smoothly connect the housing component 22 and the bearing platform 112. In this embodiment, the first mounting hole 4111 is a round hole, and the second mounting hole 4211 is a long hole extending in the vertical direction. In other embodiments, the first mounting hole 4111 may be a long hole extending in the vertical direction, and the second mounting hole 4211 may be a round hole, or both the second mounting hole 4211 and the second mounting hole 4211 may be long holes extending in the vertical direction.

[0087] like Figure 2As shown, the shell mechanism 20 also includes a first adjustment component 23, which is connected to the bottom plate component 21 and is used to adjust the height of the bottom plate component 21 (i.e., the height relative to the support surface on which the main body mechanism 10 is supported). By setting the first adjustment component 23 to adjust the height of the bottom plate component 21, not only can the shell mechanism 20 better cooperate with the disassembly and assembly of the connection mechanism, and improve the convenience of debugging before and after transportation of the 3D printer; but also during transportation, the lower end of the shell mechanism 20 can be suspended by the first adjustment component 23, so as to avoid damage between the main body mechanism 10 and the shell mechanism 20 due to the interaction of the connection mechanism due to asynchronous vibration when the road is bumpy.

[0088] In this embodiment, the housing mechanism 20 includes four first adjustment components 23. The four first adjustment components 23 can not only adjust the height of the base plate component 21, but also level the base plate component 21, thereby ensuring the stability of the support of the housing mechanism 20. In other embodiments, the housing mechanism 20 can also be provided with three or more first adjustment components 23. Specifically, Figure 2 As shown, the first adjustment assembly 23 includes a base 232 and a screw 231, wherein the screw 231 is threadedly matched with the bottom plate assembly 21, the base 232 is connected to the lower end of the screw 231 and is used to contact the support surface, and the distance between the base 232 and the bottom plate assembly 21 can be adjusted by rotating the screw 231. When the base 232 is supported on the support surface, the height of the bottom plate assembly 21 can be adjusted by rotating the screw 231, and when the bottom plate assembly 21 is connected to the main mechanism 10, the base 232 can be suspended by rotating the screw 231.

[0089] like Figure 2 As shown, the main mechanism 10 also includes a second adjustment component 12, which is installed below the support platform 11. The second adjustment component 12 can adjust the height of the support platform 11. In this embodiment, the main mechanism 10 includes four second adjustment components 12, and the support platform 11 can be leveled by adjusting the four second adjustment components 12 respectively, ensuring that the printer body on the support platform 11 can be supported in an accurate posture. The specific structure of the second adjustment component 12 is the same as the specific structure of the first adjustment component 23, and will not be repeated here.

[0090] This embodiment also provides a 3D printer transportation debugging method, which is applied to the above-mentioned 3D printer. The 3D printer transportation debugging method includes debugging before transportation and debugging after transportation, wherein:

[0091] The commissioning before transportation includes the following steps:

[0092] S110, adjusting the base plate assembly 21 to a first height through the first adjustment assembly 23;

[0093] S120, placing at least part of the connecting mechanism between the main body mechanism 10 and the shell mechanism 20;

[0094] S130, adjusting the bottom plate assembly 21 to a second height through the first adjustment assembly 23, so that the bottom plate assembly 21 is in contact with the connection mechanism;

[0095] S140, fixing the connection mechanism to the housing mechanism 20 and the bottom plate assembly 21 respectively.

[0096] During the debugging process before transportation of this embodiment, the bottom plate assembly 21 is first adjusted to the first height by the first adjustment assembly 23. At the first height, after the first extension portion 312 of the first connecting member 31 overlaps the crossbeam 1111 of the support frame 111, the lower surface of the bottom plate assembly 21 does not contact the bottom 311 of the first connecting member 31, thereby facilitating fine adjustment of the position of the first connecting member 31 along the horizontal direction (i.e., the third direction); when the approximate position of the first connecting member 31 along the third direction is adjusted, the bottom plate assembly 21 is adjusted to the second height. At the second height, the lower surface of the bottom plate assembly 21 contacts the bottom 311 of the first connecting member 31. At this time, the first connecting member 31 and the bottom plate assembly 21, the first connecting member 31 and the support platform 11 are respectively connected by fasteners, and the second connecting assembly 40 is respectively connected to the outer shell assembly 22 and the support platform 11 by fasteners. At this time, the outer shell mechanism 20 and the main body mechanism 10 are in the first connected state.

[0097] It is understandable that, during the transportation of the 3D printer, the first adjusting component 23 can be adjusted to be suspended in the air or in contact with the supporting surface of the supporting body mechanism 10 .

[0098] Preferably, during the debugging process before transportation, before the first connecting member 31 is fixedly connected to the shell mechanism 20 and the base plate assembly 21 respectively by fasteners, step S150 is performed to adjust the position of the connecting mechanism relative to the main mechanism 10 and the shell mechanism 20 by positioning members. This step can assist in adjusting the position of the first connecting member 31 along the third direction, thereby improving the installation efficiency of the first connecting member 31, and further improving the efficiency of the debugging process before transportation.

[0099] The commissioning after transportation includes the following steps:

[0100] S210, adjusting the first adjustment component 23 until it contacts the support surface;

[0101] S220, releasing the fixed connection between the connecting mechanism and the housing mechanism 20 and the bottom plate assembly 21;

[0102] S230, adjusting the bottom plate assembly 21 to a third height through the first adjustment assembly 23, so that the bottom plate assembly 21 is separated from the connection mechanism;

[0103] S240 , removing the connection mechanism from between the main body mechanism 10 and the shell mechanism 20 .

[0104] During the debugging process after transportation of this embodiment, the first adjustment component 23 is first adjusted to make it contact with the support surface. After the fixed connection between the connecting mechanism and the shell mechanism 20 and the bottom plate component 21 is released, the shell mechanism 20 will not fall, thereby avoiding damage to the shell mechanism 20. After the connection between the connecting mechanism and the shell mechanism 20 and the bottom plate component 21 is released, the bottom plate component 21 is first adjusted to the third height to separate the bottom plate component 21 from the first connecting member 31. At this time, the bottom plate component 21 no longer applies force to the first connecting member 31, thereby smoothly removing the first connecting member 31 from between the main mechanism 10 and the bottom plate component 21. At this time, the shell mechanism 20 and the main mechanism 10 are in the second state of separation. It should be noted that the first height and the third height can be the same height or different heights, which are not specifically limited here.
